The average price recorded in Andrésy stands at 3 266 €/m². That average covers a mixed residential stock, where detached houses, often sought after along the Seine and on the hillsides, sit alongside blocks of flats present around the station and the centre. It includes former bourgeois holiday houses, twentieth-century detached homes and more recent developments. The price level sits within the range of the municipalities of this bend of the Seine, below the most highly rated addresses of western Paris but above the towns further from the metropolitan area. The gaps around that average come mainly from the type of property, the view and proximity to the Seine and to the station. These figures come from the DVF database, which records the sales actually signed before notaries, and give a municipal benchmark to be refined property by property.

The Andrésy market rests on its setting as a riverside town on the Seine and on its direct rail service to Paris, two assets that support demand in western Île-de-France. Buyers, often families and working households of the metropolitan area, look for a compromise between access to Paris on Line J and an environment more residential than the inner suburbs. The presence of the river, the hillsides and the île Nancy adds to the appeal of the municipality and weighs on the best-located properties.
Supply consists of a mixed stock, between detached houses spread along the Seine and on the hillsides and apartments concentrated around the station. Available land is limited in an area already largely built up, which contains the contribution of new build. On the resale market, energy performance has become a marked bargaining point, notably on the old holiday houses. Buyers weigh proximity to the station, a view over the river and floor space against one another according to their plans.
Set facing the confluence of the Seine and the Oise, Andrésy shows prices close to those of Conflans-Sainte-Honorine and Cergy, below Poissy and far from the most highly rated addresses of western Paris.
Andrésy is a former riverside town on the Seine, set on a bend of the river, facing the confluence of the Seine and the Oise. Its history goes back to the Middle Ages, a period attested by the church of Saint-Germain, a building whose oldest parts date from the twelfth and thirteenth centuries. Its position on the river made Andrésy a place of passage and exchange, turned towards navigation and towards the vine-planted hillsides that once overlooked the village.
Like other municipalities of the Seine bends downstream from Paris, Andrésy saw the rise of holiday living in the nineteenth century. The arrival of the railway and the Parisian taste for the banks of the river encouraged the building of bourgeois houses and villas along the Seine, in a landscape of waterside and islands that inspired the painters of the period. Riverside dance halls and leisure activities tied to the river accompanied that transformation of a farming village into a place of residence and of strolling.
Andrésy is also marked by the île Nancy, an island in the Seine attached to the municipality, preserved as a natural space and open to the public. Laid out as a park with a contemporary art trail, it forms a distinctive green lung in the middle of the river. In the twentieth century, the municipality became part of the conurbation of the Seine bend and today belongs to a dense urban area of western Île-de-France, while keeping its identity as a riverside town.
Andrésy has 13 834 inhabitants according to the latest census. Its housing stock is more given over to detached homes than in the densest neighbouring towns, with a large share of individual houses spread along the Seine and on the hillsides, complemented by blocks of flats concentrated around the station and the centre. The municipality attracts mainly families and working households of western Île-de-France, drawn by the riverside setting and by the rail service to Paris. Buyers often look for a compromise between access to the capital and an environment more residential and greener than the inner suburbs. First-time buyers lean rather towards apartments close to the station, while houses, in particular those with a view or access to the river, are aimed at higher budgets.
The average value recorded from notarised sales is 3 266 €/m². That figure aggregates varied properties, from an apartment close to the station to a house on the hillsides or by the Seine. The type of property, the location, the view, the year of construction and the energy certificate explain most of the gaps around that average. For a reliable valuation, it is better to rely on sales of comparable properties than on the municipal average alone.
Andrésy has its own station, served by the Transilien on Line J, which connects the municipality to Paris Saint-Lazare via Conflans-Sainte-Honorine. That rail service is one of the assets of the municipality for people working in the capital. Andrésy is also linked to the neighbouring towns of the Seine bend and to the main roads of western Île-de-France, which makes travel around the conurbation easier.
The île Nancy is an island in the Seine attached to Andrésy, preserved as a natural space and laid out as a park open to the public. It hosts a contemporary art trail that converses with the vegetation and the river. It is an emblematic place for walking in the municipality, and it adds to its quality of life as a riverside town. Its presence contributes to the residential appeal of Andrésy, in particular for the sectors close to the river.
Both formats coexist in Andrésy. Houses, spread along the Seine and on the hillsides, offer space and sometimes a view over the river, but are aimed at higher budgets. Apartments, more concentrated around the station and the centre, suit first-time buyers and those who put the rail service to Paris first. The choice depends on your budget, on your need for outdoor space and on how much weight you give to proximity to the station.
Like all municipalities bordering the Seine, Andrésy has sectors close to the river that may be concerned by flood risk. That information should be checked in the statement of risks and in the planning documents before any purchase, notably for properties on the riverbank. The hillside sectors, higher up, do not carry the same exposure. These points deserve to be looked at case by case according to the exact address of the property.
